7'0 allwhom it may concern: j

Be it known that I, ADoLrH PFEIFFER, subject of the present Governmentof Russia, residing at Chicago, inthecounty of Cook and StateofIllinois, have invented certain new andjuseful Improvements Clasps, of

whi'th the following is a specification.

. nected r r This inventionrelates to improvements in clasps,particularly adapted, though not necessarily limited inits use as-aSuspender claspand one of theobjects of the invention is to provide animproved clasp of this character which will beeffective and eflicientinoperation and. which will securely hold the article tofwhioh it is tobe con- A further object is to provide an improved clasp of thischaracter j having meansfor locking or seculing the fastening lever 01'member against accidental movement about its pivot.

To the attainment of these ends and the accomplishment of other new anduseful ob- .jects as will appeanthe invention consists n the features ofnovelty in substantially the construction, combination andarrangement ofthe several parts, hereinafter more fully described and claimed andshown in a so the accompanying drawing illustrating this the clasp in anopen position- Fig. 4 is a side elevation of Fig. 3. Fig. 5 is a viewsimilar to Fig. 1 ofanother formof theinvention.

Fi 6 is a sectional view taken on line 6-6 ig. 5. I o

Fi .7 is a View" similar to Fig. 5 showlng the c asp in an openposition.

Fig. 8 isa side elevation of Fig. 7.

Referring more particularly to the draw ing the clasp consists of a bodyportion constructed of any suitable sheet material such as metal bentback upon itself to form the i spaced portion 10 and 11 and in order toor being contracted, a suitable fastening device 12 may be provided. Theportlon 10 of hold the parts in such position and to revent the members10 and 11 from sprea mg the body, in the form of the invention shown inFigs. lto 4, is provided with any desired number of elongated aperturesor openings about its Specificationcf Letters fatcnt. Patented N 15 1921Application flledhugust 28, 1920. Serial No.'405,369.

13 therethrough and rojecting beyond the portion 10 are spaced ears 14,which are preferably arranged adjacent one end of the portion 10. a

Pivotally mounted to the earsl l is a lever or element15 which isprovided with prongs or teeth 16 adapted to be projected through theopenings 13 when the lever 15 ismoved pivot in such a direction as tocause the ever 15 to rest against or stand in close proximity to theportion 10 of the body. Connected with the lever 15 at any desired pointpreferably adjacent its free end is acatch 17 of anyfdesired construction; This catch is adapted, when the lever 15 is moved intothepositionshown in Figs.

1 and 2, to enter an opening 18 in theportion 10 of thebody and tocooperate with one of 'the walls ofthe opening 18 after yieldinglylocking the lever 15 against movement about its pivot.

If desired, the free end of the portion 11 of the body may be bent backupon itself as at 19 to form a shoulder with which the ends of theprongs or teeth 16 cooperate.

In use the clasp maybe connected to a suspender, a portion of which is,designated as at20 or to any other suitable-portion of a garment, in anydesired. manner such as by means ofa link 21 which passes through theopening 22 formed between the portions 10 and 11 of the body and thefastening device 12. The lever 15 is moved into the position shown inFigs. 3 and 4 and the garment or elementto which the clasp is to beattached is inserted. between the portions 10 and llof the body afterwhich the lever 15 is moved about its pivot into the position shown inFigs. 1. and 2 so that the prongs 16, will either penetrate or be forcedagainst the surface of the inserted element to force the latter againstthe portion 11 of the body for securely holding the element, the catch17 entering theop ening 18 and locking the lever 15 against movement.The shoulder 19 formed on the end of the portion 11 cooperates with theprongs 16 to frictionally hold the element against displacement withrespect to the clasp. In the form of the invention shown in Figs. 5 to 8the portion 10 of the body is toothed members 25 secured thereto in anydesired manner such as by means of fastening devices 26 or, if desired,these teeth 25 may be welded to the lever 15 or may be formed integraltherewith.

The inner face of the portion 11 of the body is provided with a seriesof corrugations or serrations adapted to cooperate with the corrugatedor serrated edges 28 of the teeth 25. 1

This form of theclasp is used in the same manner as the form shown inFigs. 1 to 4 and when the lever 15 is moved into the position shown inFig. 6 the material will be frictionally gripped between the serratedfaces 28 of the teeth 25 and the serrations or gOI'rugatiOnS 27 on theportion 11 of the hile the preferred form of the invention has hereinbeen shown and described, it is to be understood that various changesmay be made in the details of construction and in the combination andarrangement of the several parts, within the scope of the claims withoutdeparting from the spirit of this 1 invention.

What isclaimed as new is A clasp embodying a substantially U shaped bodyportion, a reinforcing fastening device connected with the members ofthe U to extend across the space therebe-.

tween, said fastening device being spaced from the bend of the bodyportion to form a suspension eye or opening, portions of one portion,corrugations extending transversely of the last recited member and withwhich corrugations the toothed members cooperate, and a catch carried bythe said lever and adapted to cooperate with an edge of one of themembers of the body portion for yieldingly locking the lever againstmovement with respect to the said body.

In testimony whereof I have si ned my name to this specification, onthis 21st day of August, A. D. 1920.

ADOLPH PFEIFFER.
